Number of
APs

This visualization shows how
many APs cover the given area. An area is considered covered
if the signal is strong enough for the clients to communicate with
the AP. In many WLANs, multiple AP coverage is an important
requirement that ensures uninterrupted connectivity, load
balancing, and seamless roaming. If this requirement exists in your
WLAN, you can use this visualization to make sure that AP coverage
areas sufficiently overlap.

As in theAP Coverage
Areasvisualization,
the definition of “strong enough” is rather subjective because
certain signal strength might be sufficient for low data rates, but
insufficient for the high data rates required for such applications
as VoIP. Additionally, 802.11 adapters vary in sensitivity, and
some adapters might be able to provide good connectivity in zones
where other adapters fail to connect altogether. TheVisualization

theArea is considered
covered if signal strength is at leastsetting, which defines the AP coverage area
based on the minimum signal strength. If the signal strength is
below the specified level, the area is considered to be not
covered.

Double-clicking on the Number
